TL;DR: In this paper, the authors found that the viscous electron fluid in graphene responds to nonquantizing magnetic fields by producing an electric field opposite to that generated by the ordinary Hall effect.

TL;DR: In this paper, the transition between the two regimes is characterized by a sharp maximum of negative resistance, probed in proximity to the current injector, and the resistance decreases as the system goes deeper into the hydrodynamic regime.

TL;DR: In this paper, the magnetization of two-dimensional ferromagnetic crystals is measured using a multi-terminal Hall bar made from encapsulated graphene. But the magnetic response of CrBr3 varies little with the number of layers and its temperature dependence cannot be described by the simple Ising model of 2D magnetism.

TL;DR: It is shown that the bulk electronic states in such rhombohedral graphite are gapped and, at low temperatures, electron transport is dominated by surface states, and spontaneous gap opening shows pronounced hysteresis and other signatures characteristic of electronic phase separation.

TL;DR: In this article, the authors study electron transport through a helical network and report giant Aharonov-Bohm oscillations that reach in amplitude up to 50% of resistivity and persist to temperatures above 100
